ALBERT KOMP, OF NEW YORK, N. Y.

IMPROVEMENT IN BRAIDING-GUIDES FOR SEWING-MACHINES.

Specification forming part-of Letters Patent No. ll0,37-1, datedDecember 20, 1870.

To all whom it may concer-n:

Be it known that I, ALBERT KOMP, of the city, county, and State ot' NewYork, have invented a new and Improved Braid-Guide for Sewing-Machines;and [do hereby declare the following to be a full, clear, and exactdescription thereof,which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part otl this specification, in which drawings- Figure 1represents a sectional front view oi' this invention as applied to asewing-machine. Fig. 2 is a detached plan ofthe guide. Fig. 3 is alongitudinal section of the same. Fig. 4 is a transverse section of thesame.

Similar letters indicate corresponding parts.

This invention consists in the arrangement, in the throat-plate of asewing-machine, ot' a slot extending from one end of the throat-plate tothe throat, and composed ot' aat part running parallel, or nearly so,with the surface of the throat-plate, and of anarrow slit extend- --ingfrom said tlat part up to the surface of the throat-plate in such amanner that the wide part of the slot forms the guide for a braid, whichcan be readily and conveniently crowded through the narrow upright partof said slot, and by these means a braid-guide is obtained which isexceedingly simple and convenient in its operation and construction,requiring no extra part to be attached tothe sewing-machine, and whichdoes not in any way interfere with the ordinary functions of the sewingmechanism.

`ln the drawings, the letterA designates the throat-plate ot'asewing-machine,which is situated below the needle, being inserted intothe cloth-plate of the machine in such a manner that one or both endsthereof are iiush with the edge of the cloth-plate or with that of anelevation rising from said cloth-plate, as may be desirable. From thethroat a of said throatplate extends an inverted-T-shaped slot, b, in adirection opposite to that in which the feed lakes place, and clear outto the end of said throat-plate, as shown in Figs. l, 2, and 3, theshape of the slot being best shown in Fig. 4. By inspecting theseiigures it will be seen that the narrow upright part of said slotextends up to the surface of the throat-plate, so that a braid can bereadily crowded down through said part into the hat horizontal part ofthe slot, which latter part forms the guide for the braid. From the sideof the throat oppositey the T-shaped slot extends a channel,c,gradu allydiminishing in depth from the throat up for the purpose of preserving aneven surface ofthe work under the presser-foot of the sewing-machine.The vertical portion of the T- shaped slot, which is made to open on theface ofthe plate, permits the ready introduction ot' the braidsidewise,which not only affords ready means of inserting the braid intothe guide, but holds it in position. By taking hold ot' the braid withtwo hands and stretching it out over and then depressing it on thethroatplate said braid can be readily forced down through the uprightportion ot' the slot b, and after having passed through this part ot'the slot the braid naturally spreads in the tlat horizontal partthereof, which part forms the guide for the braid during the operationot' sewing.

This braid-guide is very simple inits construction. It requires no eXtrapart to be attached to the sewing-machine, and it does not in the leastinterfere with the ordinary functions ofthe sewing mechanism.

Itis obvious that the narrow upright part of'the slot might be madeinclined or curved without changing the result.

l am aware that extra plates have been hitherto employed, which platesare made to be removed from the face of the throat-plate in. order tointroduce the braid in the guiding-slot, and are thenreturned to theiriirst position to hold the braid in said guiding-slot. Such I do notclaim; but

What l claim as new, and desire to secure by Letters Patent, is

The th roat-plate A,formed in one piece with the inverted-T-shaped slotb, having the vertical portion thereot' opening on the face of saidplate, and the horizontal portion communicating therewith below theface, all as set forth, for the purpose described.

This specification signed by me this 29th day of October, 1870.

A. KOMP.
